GZ 125 exhaust tuning?

I ask from a pure interest. I ask you not to have to read “buy another moped”, I hear that too much. I have a GZ125 of 98, all my pride, I am optically but not necessarily a fan of the slanting high outpuff. I had also once organized a GN125 exhaust for the bender, if I should find a sound damper the legal on it.. but did not find it myself. As far as I know there are no exhaust systems for the GZ125 marauders, the legal i There are sports exhaust systems such as sand on the sea, also for the VZ800 Marauder there are systems.. but nothing for the GZ125. Are there any options? Are there not ways to have special silencers made? Or are there ways to make another exhaust legal with examination? Thanks in advance for the answers!
